SWINGING GATE.

SPECIFICATION forming part of Letters Patent No. 313,976, dated March 17, 1885.

Application fi'ed May 2'), 1884. (No model.)

To all whom, it may concern:

Be it known that we, GROVE S. BARTHOLO- NEW and J OHN D. ABBOTT, of Reading. in the county of Hillsdale and State of Michigan, have invented certain Improvements in Swinging Gates, of which the following is a specification.

The object of the invention is to so improve swinging gates that they may be easily raised, swung open, latched, and prevented from sagging. The means by which these objects are attained will first be described in connection with the drawings, and then pointed out in the claim.

Figure l of the drawings is a side elevation with a part of the balance-lever broken away to show the form of hole which receives the upper end of the hinge-pintle, also showing the gate latched and in its normal position. Fig. 2 is also a side elevation showing the latch pressed back and the gate raised preparatory to being swung open. Fig. 3 is a detail.

In the drawings, A represents the rails longitudinally arranged in vertical end uprights, and provided with a median upright, e, which extends alternately on opposite 'sides of said rail, so as to follow the central line of gravity and then rises above them, so as to be connected by a pivot directly with the counterbalancelevcr B. This lever hasa pivot-hole, c, which diverges outwardly toward each end of the lever, so that the latter will have room for playing back and forth as it is vibrated in raising and lowering the gate.

1) arelong or slotted hinges which clasp loose ly the pintle f and give it about two inches play back and front, and which slide up and down on it, the extent of their movement being limited horizontally by the length of the slot or opening in the hinge, and perpendicularly by the standard a, whose extension t is made fast to a rigid post, 0.

j is a wire or small rod of iron fastened tightly to the side of the pintle f and extending lengthwise thereof on the side toward the rigid post 0, so that when the gate is raised or lowered at the front end the back side of the long or slotted hinge 1) comes in contact with this wire or rod of iron and is raised or lowered with little friction.

(1 represents the latch of the gate, whicl slides back and forth in a keeper, 9, on the I it on a rearward and upward incline, so that it will have a constant tendency to slide down. Thus it will be perceived that no spring is necessary to keep it in its position and fasten the gate to the front post.

By jointing my lever directly to the median upright e, passing that upright through the rails so as to be alternately on opposite sides thereof, and fulcruming the counterbalance-lever on the hingepintle, we balance the gate with great exactitude, and by stretching the wire on the back side of the hinge-pintle the gate will always rise easily at the front end.

Rising and swinging gates with close hinges and without the wire usually sag forward or bind at the hinges when raised at the front end, so as to create a great deal of friction. In practice our gate is entirely free from this objection.

Also, it will be observed that our standard a performs two functions namely, to support the pintle, (the standard a may be a part of the pintle left square in the center,) and, secondly, to regulate the distance which the hinges may travel. ly it determines the height to which the gate may rise and to which it may return.

I am aware that it is not broadly new to pivot a counterbalance-lever on an extension of the hinge-pintle, or to connect the front end of a counterbalance-lever with the top of a middle post of the gate; but I am not aware that any one has ever combined the parts as hereinafter pointed out, so as to reduce fric- Incidentally and indirect- 8 5 tion, and to give a smooth even movement to l above said post, the median upright e, and fo the gate, vertically as well as horizontally. i the counterbalance-lever B, pivoted to said Hence, l uprightas well as recessed at c, substantially NVhat I consider new and of my invention as and for the purpose specified.
